CHECK-ROWING ATTACHMENT FOR SEED-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 299,981, dated June 10, 1884.

(No model.)

To all whom it may concern.-

Be it known that I, PI-IILANDER HINKL-EY,

a citizen of the United States, residing at Charleston, in the county of Goles and State of Illinois, have invented a new and useful Improved Oheck-Rowing Attachment for Seed- Planters, of which the following is a specification.

My invention relates to an improved checkrowing attachment of that class which are operated by means of a knotted wire or rope stretched across the field, and which are adapt ed to operate the seed-dropping mechanism of that class of seed-planters in which the seed is dropped alternately from each of a pair of seedhoppers placed on opposite sides of the planter.

The objects of my improvements are to adapt the same check-rowing attachment to the varying stroke of the seed-dropping mechanisms of different seed-planters, and to insure the uniform movement of the checkingcam, as hereinafter explained.

The accompanying drawings illustrate my invention.

Figure 1 is aside elevation. Fig. 2 is an end elevation, showing the position of the parts at the moment the knot 011 the checkingwire engages the checkinglever. Fig. 3 is an end elevation, showing the position of the parts at the moment of the discharge of the knot from the checking-lever.

Like letters indicate the same parts.

a is a beam adapted to be secured by bolts, or in any other suitable manner, to and across the frame of a seed-planter.

To the opposite ends of beam a are secured cross-pieces c d, which form bearings for a shaft e.

Centrally located on shaft 0 is a disk, f, having on each side cam projections g.

Pivoted to beam a at h is a lever, i, the

lower end of which is adapted to engage the sliding bar j, forming part of the dropping mechanism of the planter. 45 To the upper end of lever z pair of arms,

Z Z, are secured bymeans of a pivot at m, passing through both arms and secured 1n the lever, and thumb-bolts n 0, which are adjustable along stop 12 in the lever. An adj nstable fork is thus formed on lever 6, having 011 its outer extremities friction-rolls q g, which engage the opposite sides of disk f. The purpose of said fork is to communicate more or less motion to lever z and bar j. as the distance between the friction-rollers on the armsis diminished or increased.

Secured to one end of shaft 0 are two ratchetwheels, 1' and s, and turning loosely on said shaft is a checking-lever, t, forked at the top to receive the knotted checking-line u. Lever t, as it is drawn backward, engages ratchet-wheel s by means of a pawl, 'v, pivoted to said lever. A pawl, 10, is pivoted to crosspiece 0 in such a position that as lever tis drawn backward an inward projection, w, thereon catches under pawl 20 and raises it so that at the moment lever t has completed its backward movement pawl w engages ratchetwhecl r and prevents shaft 0 and cam-disk f from turning farther.

1 (1 and z are guide-wheels for the knotted line a.

The operation of my device is as follows: As the planter moves forward, to which the check-rower is attached, the lever t is in the position shown in Fig. 2. When a knot in the checking-line engages lever t, it is thrown into the position shown in Fig. 3, thereby turning shaft e and cam-disk f by means of a pawl, o, and ratchet-wheel 8. At the same time pawl 80 wis raised by the lower end of lever t, and ratchet r is engaged, as before explained, thus preventing the momentum acquired by disk f from carrying it beyond the desired movement. When lever t reachesthe inclination shown in Fig. 3, the knot slips over the end of the lever, and the lever is returned to its normal position by a spring, 1. As disk f revolves, the cams g thereon successively engage on alternate sides with the frictionrollers on the ends of arms Z Z, thereby vibrating lever t, and giving a reciprocating motion to bar j. It is obvious that if arms Z are brought together so as to touch disk f 011 both sides at once, leverz' will receive the full throw of 5 cams 9; but if the arms are spread wider apart the movement of said lever and bar will be to and adjustable thereon, thereby forming an adjustable forked extension of said lever,

substantially as and for the purpose specified. 1o

I claim as my invention and desire to seeure by Letters Patent-- In a cheek-rowing attachment for seedingmaehines, the combination of cam-disk f and vibrating lever i, having arms 21 pivoted there- Vitnesses:
